Schir haSchirim 7:3 Kabbala: Zohar, Sha'arei Orah & Tikkunei Zohar

Now if that redeemer is not willing to establish seed for his brother in this world, he must tie a shoe on his foot and the wife must loosen it and take it to herself. Why was a shoe chosen for this purpose? Because the shoe was the support of the dead man in this world, and the woman, by taking it, signifies that the dead man who was wandering about among the living

Therefore, wherever in Torah you find the name God-Elohi”m-אלהי״ם, contemplate and know that this refers to HaShem’s-יהו"ה quality that comes to render justice and judgement upon the whole world. In the previous gate we already have informed you that the Great Upper Sanhedrin is positioned between His Name HaShem-יהו״ה and His name God-Elohi”m-אלהי״ם, and how the quality of mercy-Rachamim is intermingled with the quality of judgment-Din, so that creation will not be utterly destroyed in judgment. Thus, the Upper Sanhedrin is affixed to the left, between the Name HaShem-יהו״ה and the name God-Elohi”m-אלהי״ם, leaning toward the left. About this the verse states,⁵Song of Songs 7:3 “Your navel-Sharereich-שררך is like a round goblet, let blended wine not be lacking,” to which our sages, of blessed memory, stated,⁶Talmud Bavli, Sanhedrin 37a – See there for the full explanation of the verse, as it relates to what is stated here. “This refers to the Great Sanhedrin.” Because the verse states,⁷Ezekiel 1:10 “The face of the ox-Shor-שור on the left,” the Great Sanhedrin is therefore called, “Sharereich-שררך.”⁸The term “Sharereich-שררך” is spelled with the letter Shin-ש, but is also of the same root as “minister” or “ruler” – “Sar-שר,” and “authority” or “dominion” – “Srarah-שררה,” with the letter Sin-ש.

"Your neck is an ivory tower" (Song of Songs 7:3) - this is Jerusalem, as it is written (4:4) "Like a tower of David is your neck..." - her adornments are the priests, Levites and Israelites; "... built as an armory (talpiot)" - this is the Righteous One who is a hill (tel) towards which everyone faces (ponim), and whose points are the true prophets. For the Shechina is surely Jerusalem, adorned by the three forefathers, bejewelled with the foundations of truth.
